Technology: A Rheological Master Curve for the Viscosity vs. Solids Relationship of Water Borne Adhesive Polymer Formulations µ = µ0*(1+ Ø* Xvol) µ = the viscosity of the system Ø = Shape Factor, a constant µ0 = the viscosity of the aqueous medium Xvol = The Volume Solids of the system

The viscosity of any polymer dispersion system is heavily dependent upon the particle to particle interactions of the system. Einstein famously developed an equation which predicted the viscosity vs. solids relationship of a dispersion of hard spherical particles at low solids.

The shape factor, Ø, for a distribution of uniform hard round spheres is the value 2.5.

The validity of this model is best when the volume solids content is about 5% or less. At higher solids any model must include higher terms to account for the increased particle to particle interactions. Because adhesive polymer systems and formulations are soft spheres which deviate from Einstein’s assumptions, the agreement to the hard sphere equations is limited. A way to model the viscosity of soft spheres not only has benefits in adhesives, sealants and coatings but also possible medical implications along with other uses in other water borne polymer markets. The basic knowledge of how the viscosity profile of a water borne formulation changes with solids can speed formulation research and development incredibly and increase the understanding of how adhesives perform. After numerous trials, the best equation for fitting the solids / viscosity relationship is of a form similar to the actual Einstein equation itself: if Z = (1+ Ø* Xvol)

Then the Einstein solution is: µ = µ0*Z

While the higher solids model is: µ = µ0*Z^Z

Replacing Z with its definition the model is: µ = µ0*(1+ Ø* Xvol) ^ (1+ Ø* Xvol)

This model, based on only two degrees of freedom, has a better fit than others using higher degrees of freedom. Using the same variables, shape factor and volume solids, and degrees of freedom as the Einstein model, this equation can predict the solids / viscosity of an adhesive formulation at higher solids once the shape factor for the particle size distribution is determined.

Avery Dennison

Technology: The Advanced Acrylics Technology for High Performance Pressure Sensitive Adhesive Applications

The Advanced Acrylics (AAc) technology is a patented high performance pressure sensitive adhesive technology developed at Avery Dennison’s Polymers, Adhesives and Coatings CoE (PACE) research facilities at Mill Hall Pennsylvania over the last several years. The technology combines controlled radical polymerization within emulsion systems with polymerizable surfactant technology to deliver emulsion PSA that is replacing high performance solvent-based PSA in many applications. A significant milestone was the successful scale up to production scale of the AAc adhesive emulsion process during February/March 2021, to facilitate product introduction within the European market.

Technology: Avery Dennison’s CleanFlakeTM sustainable adhesive: Enabling recycling of PET bottles

Plastic contamination of our environment is a growing problem. Consequently, several companies like Avery Dennison have stepped up to the challenge by setting ambitious sustainability goals to help stem the tide of plastic pollution. Avery Dennison’s CleanFlakeTM adhesive technology is in line with our goal to deliver innovations that advance the circular economy by facilitating the effective recycling of PET bottles. Avery Dennison’s CleanFlakeTM technology works by enabling the complete removal of labels leading to unblemished food grade recycled PET resins which can be used for bottle to bottle manufacturing. This is achieved without any disruption to the current recycling process. In addition to complete label removal, Avery Dennison’s CleanFlakeTM adhesive maintains improved water whitening resistance, excellent converting and consistent tropical stability. The improvements built into Avery Dennison’s CleanFlakeTM adhesive makes it an innovative solution which addresses the ever evolving demands of the packaging industry.

Technology: Bostik’s First to Market Gauged

Porcelain Tile Pane Adhesive: Bosti-Set

Bosti-Set™ is a new-to-the-world adhesive technology launched by Bostik’s Consumer & Construction Business Unit. It was conceived by way of a strategic collaboration with Crossville Inc, a world-leading manufacturer of tile products. Bosti-Set™ is a disruptive innovation that is changing the method and materials used to install thin (or Gauged) Porcelain tile Panels (GPP) on walls. Bosti-Set™ is faster, safer, and easier to use than traditional mortars. Compared to mortar, installation with Bosti-Set™ takes roughly ¼ the man-hours, produces no dust, weighs 80% less, consumes no water or electricity, enables first to the market acoustic benefit for wall tile installations, and allows new applications and substrates for GPP.

Be proactive & responsible citizens

Recent changes to the OSHA regulations have nearly cut in half the allowable amount of respirable silica dust exposure on job sites. Bosti-Set™ is dust-free and contains 0 VOC’s. It is lighter and holds better than mortars, so it is also safer for installers, especially working at heights. The formulation uses recycled rubber as an aggregate, sound dampening aid, and as a gauged for even bed depth of the adhesive. This reduces call backs due to lack of coverage for the installing contractor and at the same time ensures that the contractor does not over embed the adhesive which could cause hollow spots behind the tile that could then result in damaged tiles that would require replacement.

Technology: Thermogrip H43298

Compostable Adhesive - The World’s First High Performance Compostable Hot Melt Adhesive

Thermogrip H43298 was developed to address the aspirations of many leading brand owners for 100% recyclable, reusable, or compostable packaging by the mid 2020’s. Initially developed for doublewalled hot beverage cups, this hot melt adhesive (HMA) became the first to gain BPI-certification. This certification ensures the adhesive will degrade in industrial composting facilities and at the same time offers a robust temperature performance window, which makes it suitable for “hot and cold” beverage applications, and case and carton sealing for food packaging applications.

Clariant Corporation

Technology: AddWorks® IBC 760, a high performance, hazards free solution to increase light and heat stability in SMP sealants

Over the last two decades, the sealant industry has been facing an ever-growing demand for increased durability (1) of their products for a broad range of applications such as: joint seals in buildings, metal to metal bonding and glass to metal adhesives for automotive applications. Recently, the classification & hazards labelling of the most common light and heat stabilizers additives used in sealants and adhesives is under increased scrutiny. Regulatory authorities across many regions are expected to further add restriction to those chemicals. Such regulatory changes are not only impacting the labelling of the light and heat stabilizer additives but more importantly, the labelling of the final product itself. By combining their technical expertise, Clariant and Omya formed a partnership to develop a unique and novel solution to address these issues and respond to the growing need from within the industry to create more sustainable and outperforming hazards free solutions. AddWorks® IBC 760 is a micronized powder which prolongs the service life of adhesives and sealants as it reduces cracking and yellowing that typically occurs if exposed to sunlight or high temperature conditions This new stabilizer solution is an ideal ingredient to formulate high performance adhesives and sealants used for construction, automotive and other outdoor or high heat temperature applications. The performance is evident when tested against current market standard (benzotriazole UVA/HALS/AO) with a significant increased weathering durability and heat resistance. AddWorks® IBC 760 is the only label-free solution which provide safer handling for all formulators, production staff and end users.
